Synthesis of sitophilate 6, the male-produced aggregation pheromone of
the granary weevil, has been achieved with an overall yield of 46% fr
om 1 in high enantiomeric and diastereomeric purity. From sitophilate,
sitophilure 8, aggregation pheromone of the rice weevil and maize wee
vil, was prepared in a four-step synthesis without any racemization. C
